Slide fastener slider with detachable pull tab

Abstract

A slide fastener slider comprises a slider body, a pull tab support pivotally connected at one end to the slider body, and a pull tab removably attached to the opposite end of the pull tab support. The pull tab support comprises a hook portion hooked to define therein a gap for loosely receiving an annular portion of the pull tab and having in its inner surface engaging means; and a substantially U-shaped resilient member having at its opposite ends fitting means for fitting engagement with the engaging means, to thus close the gap.

What is claimed is: 
     
       1. A slide fastener slider comprising a slider body, a pull tab support pivotally connected at one end to the slider body, and a pull tab removably attached to the opposite end of the pull tab support, said pull tab support comprising: a support body including a peripheral wall defining therein an aperture for the pivotal connection to the slider body, a beam lying substantially in the plane defined by the arcuate shape of the peripheral wall and linking confronting ends of the peripheral wall and a hook portion including an upper wall extending from the confronting ends and a lower wall hooked therefrom to define with the upper wall a gap for loosely receiving an annular portion of the pull tab, said upper wall being raised above the level of the peripheral wall to thus define an opening facing the peripheral wall between the proximal end of the upper wall and the beam, the upper wall and the lower wall having in their respective inner surfaces upper engaging means and lower engaging means; and a substantially U-shaped resilient member including an upper leg, a lower leg and an arcuate joint joining the upper and lower legs, the upper leg and the lower leg having at their respective distal ends upper fitting means and lower fitting means; the resilient member having its upper and lower fitting means brought into fitting engagement with the upper and lower engaging means, respectively, of the upper and lower wall, with its upper leg fitted through the opening in and with its arcuate joint snugly embracing the beam, so that the resilient member comes into reliable engagement with the support body to thus close the gap. 
     
     
       2. A slide fastener slider according to claim 1, the lower leg of the resilient member being bent outwardly adjacent to the distal end thereof to provide a slant foot extending obliquely downwardly therefrom. 
     
     
       3. A slide fastener slider according to claim 2, the distance between the bending point of the lower leg and the corresponding point of the upper leg being less than the length of the major axis and the length of the minor axis of the oval cross section of the annular portion of the pull tab. 
     
     
       4. A slide fastener slider according to claim 1, the upper leg being of substantially the same width as the opening. 
     
     
       5. A slide fastener slider according to claim 4, the beam having at an upper side and a lower side an upper furrow and a lower furrow, respectively; the upper furrow communicating to and being substantially of the same width as the opening; and the upper leg and the lower leg being substantially of the same width as the upper furrow and the lower furrow, respectively. 
     
     
       6. A slide fastener slider according to claim 1, the lower leg of the resilient member being provided at its distal end with an upright stopper, the distance between the top of the upright stopper and the distal end of the upper leg being less than the length of the major axis and the length of the minor axis of the oval cross section of the annular portion of the pull tab. 
     
     
       7. A slide fastener slider according to claim 1, the upper and the lower fitting means being an upper and a lower fingers provided at the respective distal ends of the upper and the lower legs of the resilient member; the upper and the lower engaging means being an upper and a lower groove formed in the inner surface of the upper wall and at the distal end of the inner surface of the lower wall, respectively, for fitting engagement with the upper and lower fingers, respectively, of the resilient member. 
     
     
       8. A slide fastener slider according to claim 1, the lower fitting means being a pair of fingers provided at both corners of the lower leg; the lower engaging means being a pair of notches formed at both corners of the inner surface of the lower wall, respectively, for fitting engagement with the fingers, respectively, of the lower leg; the distance between the fingers being slightly greater than the distance between the corner notches. 
     
     
       9. A slide fastener slider according to claim 1, the peripheral wall being arcuate.
